Four-dimensional covariant form of the conservation law of angular momentum of electromagnetic fields
The four-dimensional covariant form of the conservation law of angular momentum of the electromagnetic field is derived and its physical significance is discussed,the form is a four-dimensional second-order tensor equation with six non-zero independent components,three of which give the conservation law of angular momentum of the electromagnetic field,and the other three give both the energy and momentum conservation laws of the electromagnetic field.
